The Footprint service speeds Web site performance up to 10 times by
distributing content from a worldwide network of servers, putting Web content
closer to the consumer and shortening the delivery path. The companies said
the combined services will allow online ads to be delivered to targeted
consumers faster and more efficiently.

Financial arrangements between the companies were not disclosed.

"Footprint provides a complementary infrastructure to support AdForce's rapid
ad delivery service," said Leo Spiegel, president and chief executive officer
of Sandpiper Networks. "Sandpiper and AdForce understand online
advertisements must be delivered instantly and reliably to their target
audience to be effective."

"The synergy between the two companies is natural. We provide the advertising
management, while Sandpiper's Footprint Network increases the delivery speed
of the ads," said Chuck Berger, President and CEO of AdForce.

The Footprint network will have more than 1200 servers worldwide by year-end,
SandPiper said. Sandpiper has deployed Footprint servers in more than 20
networks worldwide, including America Online, Concentric Networks, UUnet, GTE
BBN, Sprint, Cable and Wireless, PSINet, Frontier/Globalcenter and
TCG/Cerfnet.
